[PATCH, rs6000] testsuite fixup pr96139 tests

[will schmidt via Gcc-patches]

    Hi,
      As reported, the recently added pr96139 tests will fail on older targets
      because the tests are missing the appropriate -mvsx or -maltivec options.
      This adds the options and clarifies the dg-require statements.
    
      sniff-regtested OK when specifying older targets on a power7 host.
      --target_board=unix/'{-mcpu=power4,-mcpu=power5,-mcpu=power6,-mcpu=power7,
      -mcpu=power8,-mcpu=power9}''{-m64,-m32}'"
    
      OK for trunk?
    
    Thanks
    -=Will
